The Texas Behavioral Risk Factor Surveillance System, initiated in 1987, is a federally-funded telephone survey conducted on a monthly basis of 500 randomly selected adult Texans to collect data on lifestyle risk factors contributing to the leading causes of death and chronic diseases. This is an extension of the national BRFSS, with added questions that are developed for local purposes. The site provides documentation, including counties surveyed, and copies of the questionnaires, as well as summary reports and presentations. They also map the data to state-wide health objectives.
